Traffic Applications - SURF, AIRB, etc.
The GTN ADS-B traffic display is capable of running in two “modes:”
Airborne Situational Awareness (AIRB) and Surface Situation Awareness (SURF).
AIRB is in operation in the en route environment, outside of five NM from
and 1,500 feet above the nearest airport.
SURF is in operation within the terminal environment (within five NM and
less than 1,500 feet above field elevation). When SURF is running, and the
zoom scale on the traffic display is less than two NM, the airport environment
(including taxiways and runways) is displayed in addition to traffic. This is to
aid in situational awareness of runway occupancy/availability, etc.
Due to the varying precision of the data received via ADS-B, ADS-R, and
TIS-B, all traffic targets may not be depicted on the traffic display. Because higher
data precision is required for display in the SURF environment, some targets
eligible for AIRB will not be displayed while SURF is active. Individual eligibility
for AIRB and SURF is depicted in the selected traffic data on the traffic page.
